IMPROVEMENT IN WATER-ELEVATORS.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, WILLIAM H.'CAsTLE, of Washington city, in theDistrict of Columbia, have invented a. new and useful Improvement 'inWater-Drawers; and I do herebydeclare that the following is a full andcom-4 plete description of the construction and operation of the same,reference being had to the'accompanying drawings making part of thisspecification, in which- Figure 1 is a perspective view, and

Figures 2'and 3 enlarged sections.'

Like letters refer. to like parts.

' In iig. 1, A represents the well-curb. Itmaybemade in the square,rectangular, `or any other convenient form,for supporting the windlassand other parts. B represents the windlassfshaft, which is mounted uponthe top of the curb in appropriatejournal-boxes. `C represents thewindlass, upon the shaft B, around which the rope, D, is wound, inraising the bucket, E, from the well. 'F is the spout, into which thewater isvdischarged from the bucket E. I l v The shaft B extends beyondthe curb A, on the front side, for the purpose of receiving theratchet-wheel G, which works loosely upon the shaft B.' H'represents apawl, which is pivoted to the'curb Aand engages with the ratchet-wheelGfand is held in contact by means of its own gravity. This ratchet-wheelhas a rim, I, projecting outward from the face of the wheel, as shown ings. I and 2, and which is recessed at one point, I, to receive thecrank, Ii. Y

The crank, K, where it fits'upon the shaft I3, is provided with anoblong slot, L, and is held in contact with the shaft by means of aspiral spring, M. A single tooth, N, projects from the head of the crankinwardf towards the shaft B, and engages with the teeth upon a wheel,presently to be described, the position of which upon the shaft B isrepresented by red lines in g. i2.

In figs. 1 and 3, O represents a cap, which vfits upon thc end oftheshaft B, and to which it is firmly secured by, means of the pin P, whichpasses through the collar of the cap, and through the shaft, thusfastening them together. Upon the inside of this cap O, and forming apart thereof, is a toothed wheel, Q, the position of which, when inplace, is represented by the red lines in iig. 2; and, as beforestated'7 the tooth N, upon the head of the crank, engages with the teethVof the wheel Q, in which position it is ordinarily held by the springM, and when-the crank is rotated in the direction of the arrow in thefigures, the shaft B and windlass C are rotated also, by means of theengagement of the tooth N .with any one of the teeth in the wheel Q, andby this means the bucket is raised from the well.

When it is desirable to let the empty bucket descend into the well, thecrank is drawn backward in the direction opposite tothat indicated bythe arrow, the pawl H acting as a fulcrum for the crank, and this act,by compressing the spring M, releases the tooth N from its engagementwith the wheel Q, and the bucket descends into the well by its owngravity, thereby unwinding the rope from the windlass C. When this is,accomplished, and it is desired to raise the bucket again from the well,by a movement of the crank in the direction of the arrow, the tooth Nimmediately engages with the 'wheel Q, and thereby causes the shaft Band windlass O to turn in the direction -of the arrow, and elevate thebucket. I

What I claim as my invention.v and desire to secure by Letters Patent,is-

The combination-.of theslot L, in the crank-head, the spring M, thetooth N, cap O, and toothed wheel Q, when constructed and arranged asand for the purpose set forth.

In testimony whereof, I have signed my name to this specification in thepresence of two subscribing witnesses.

WM. H. CASTLE.
